GAS-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 683,988, dated October8, 1901. p

Application filed July 22, 1901. Serial No. 69,196. (No model.) l

To @ZZ whom, it 17mg/ concern:

Be it known that I, JAMES RoDGERs, acitizen of the United States ofAmerica, residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inGas-Regulators; and I do hereby declare the following to be a full,clear, and exact description there` of, reference being had to theaccompanying drawings, which form a part of this specification.

In the employment of gas as an illuminating agent, especially naturalgas, considerable annoyance is occasioned by failure of the regulator toperform its functions in maintaining` proportionate consumption andconsequent size and intensityof flame in the burners regardless ot' thenumber of burners in or out of service.

The object of my invention is to provide a regulator capable ofoperating with either natural or artificial gases, whereby properequality is established and maintained in each and every burner.

In the accompanying drawings I have by diderent views illustrated anoperative regulator, in which my objects can be successfully carriedinto effect, wherein Figure I is a side elevation of the regulator,having its chamber-lid removed to disclose its interior mechanism andwherein parts of said chamber and mechanism are sectionally shown. Fig.Il is a vertical end view of the same with the vchamber-lid attached,said chamber and interior mechanism being sectionally shown as on line XX of Fig. I. Fig. III is a plan view of one of the valve membersdisconnected and removed Fig. IV is a plan view of both valve membersand the su pportin g-plate removed from the chamber and operativelyconnected.

In order to fully and clearly make the apparatus understood, I shalliirst proceed with and separately describe the detail parts ot'construction and then set forth the operation and effect.

Reference again being made to the several views of the drawings, thenumeral l designates a chamber of suitable form to confine the mechanismand is provided with a continuous inwardly-extended flange 2 foratt-aching a lid 3, said lid and flange having therebetween a suitablegasket 4. Openings are formed, preferably, in two opposite'side Walls ofthe chamber, one of which is Afitted with a threaded outlet-nipple 5 andthe other with a similar inlet-nipple 6, the latter nipple beingprovided with a'jam-nut 7 and gasket 8. Secured to the inner end of saidnipple 6 is the elbow 9, between the connecting end of which and theinner side wall of the'chamber is arranged a gasket I0. Threadablyattached to the upper end of said elbow is an open cylindrical valvemember Il, having thereon the annular Iiange or shoulder 12, taperingvalve-seats 13 and 14, and interior bridge 15. Engaging over thethreaded extension of said valve member, between the flange thereof andupper end of the elbow, is the supportingplate I6, havingoutwardlyextended lugs 17 thereon. Secured to said plate by nuts 19 isthe vertical adjustable standard 20, having an upper forked end, andnearby this standard, at a point between the same and the said valvemember, is secured by the n uts 18 an adjustable screw or pin 21. ed tothe upper forked end of said standard is the longitudinal bar 22, whichis provided' at one end with an elongated slot 23 and at the oppositeend with a number of closelyarranged openings 24 and slidable block 26.A circular weight or disk24i is pivotally suspended from one end of saidlongitudinal bar by a forked rod 25. This Weight or its supporting-rodis capable of being adjusted along said bar to any of the openings 24.An invertedfcup-shaped valve member 27, having tapered seats formed uponits interior and lower end to engage those of the other valve member, isprovided. A vertical stem 28 projects down from the interior of saidvalve member a sufficient distance to pass through the bridge of theother member, thereby acting as a guide to center the member and insureproper seating. To the upper end of this stem is secured an adjustableforked nut 29 to pivotally connect the slotted end of the longitudinalbar. The interior diameter of the cup-shaped valve member being greaterthan the exterior of the other member forms an annular chamber therebe-'tween.

To avoid possible friction between the Pivotally mount- IOO forked nut29 of the valve-stein and the connecting end of the longitudinal bar,due to possible swaying of the cup-shaped member when in operation, apair of lugs E30 is formed upon said member, from the under side ofwhich extend the guide-pins 31, which pass through the aforesaid lugs 17of the fixed member. A closed spiral spring 32 is connected to thelongitudinal bar and adjustable screw or pin 2l.

To install the apparatus, gas is shut off from the service-line andconnections made at the nipples 5 and G, and after the pressure has beendetermined and the weights and spring adjusted to suit such pressureacting upon the movable valve member the gas on being turned into theline will elevate the movable valve member from its seat, pass downthrough the annular chamber or space between the members, and out at thelower seat, lling the chamber and that part of the line extending to theburners, and when said chamber and line have been charged to fullline-pressure the valve will close, owing to equalization of pressure onboth sides assisted by the tension ot the spring, and remain in suchclosed condition until 'service at the burners is required.

W'hen the gas is turned on and lighted at any one of the burners, theescapement or supply of gas to such burner relieves the pressure in thechamber, and as the pressure in the line beneath the movable valvemembers is greater said pressure will act upon the member, slightlyelevating the same and permitting the gas to How therethroughproportionately or in accordance to the consumption. Should another or anumber of other burners be lighted, the valve member will be furtherelevated and permit a proportionate supply to each.

Should it occur that the pressure in the service-linebe suddenlyincreased, the valve will be prevented from quickly responding, owing tothe broad surface of the weighted disk 24 offering resistance to suddendisturbance.

The spiral spring 32 has practicallyr no tension upon it when themovable valve member is fully seated; but the tension will increase inaccordance to the lift of said member or to the number of burners inservice.

By the use of the slidable block 26, in connection with the weighteddisk 24, the most minute adjustment may be attained. It will also benoted that all essential parts of the apparatus are capable ofadjustment.

By means of this device it can readily be seen that equality may beestablished and maintained in each and every burner. Furthermore, thedevice is simple in construction and will require no attention wheninstalled.

I have specifically described the construction and relative' arrangementof the detail parts contained in a practical apparatus to effect myobjects; but I do not confine myself to any particular detail, as itmaybe possible to dispense with some of such details or substituteequivalents without departing from the principles involved.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. A gasregulator, comprisinga gas-tight chamber having inlet and outletconnections, a cylindrical valve seating member arranged therein on saidinlet, an invertedcupshaped valve member adapted to engage over and seatupon said cylindrical member leaving a space therebetween, a pivotedlever engaging at one end with the stem of said cupshaped valve member,a spring for placing tension on said lever, an adjustable weighted disksuspended from the opposite end of said lever, and means of guiding saidoupshaped member to its seat and preventing swaying thereof.

2. A gas-regulator, comprising a gas-tight chamber having inlet andoutlet connections, a cylindrical valve seating member arranged thereinon said inlet, an inverted-cup-shaped valve member adapted to engageover and seat upon said cylindrical member leaving a space therebetween,a pivoted lever engaging at one end with the stem of said cupshapedvalve member, a slidable block earried by the opposite end of saidlever, an adjustable weighted disk suspended from the same end of saidlever, and means of guiding said cup-shaped member to its seat andpreventing swaying thereof.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.

JAMES RODGERS.
